It will now be clear that I have provided a device which will accomplishthe objects of the invention as hereinbet'ore stated.

Having thus described my invention, what I claim is:

1. A closure attachment of the class described comprising an annularmember having an opening therein adapted to receive the upper end of thefilling neck of a tank, a shoulder formed adjacent said opening wherebya part of said filling neck may be bent over to secure said annularmember to said neck, a plate pivotally secured to said annular member,said plate having an opening therein smaller than the opening in saidannularmember, a cap pivotally secured to said plate and adapted toclose the opening therein, means for locking said plate in closingposition and means for locking said cap in position to close the openingin said plate.

2. A closure attachment for tanks comprising an annular member adaptedto be secured about the filling neck of a tank, a plate pivotallysecured to said annular member and having an opening therein of lessdiameter than the opening in the said annular member, a cap pivotallysecured to said plate and adapted to close the opening therein, meansfor locking said plate to said annular member and means for holding saidcap in position to close the opening in said plate.

3. A closure attachment of the class described comprising a memberhaving an opening therein adapted to receive the upper end of thefilling neck of a tank, a shoulder formed adjacent said opening wherebya part of said filling means may be bent over to secure said memberagainst removal from said neck, a plate secured to said member, saidplate having an opening therein considerably smaller than the opening insaid annular member, a cap carried by said plate and adaptedto close theopening therein, means for locking said plate in closing position andmeans for securing said cap in position to close the opening in saidplate.

In testimony whereof, I hereunto afiix my signature.
